I am using an Oracle database which has a schema name associated with it. I am able to use the SessionCustomizer override
session.getLogin().setTableQualifier(schema) to set the schema name. However, this only works for tables. When I try to call a stored procedure using a named query, it does not get honoured and I get procedure not found errors.

Thanks James. I will logon a bug as requested. I have a question with regards to your recommendation "You could also default the user's schema, so no tableQualifier is required". Is that using the orm.xml <schema>OWNERS_SCHEMA</schema> tags?
